FIG. 1 is a cross-sectional view of a semiconductor device package 1 in accordance with some embodiments of the present disclosure. The semiconductor device package 1 includes a carrier 10, an adhesive layer 30, a dielectric layer 40, a pad 60 and a conductive post 80. The adhesive layer 30 may include, e.g., conductive glue.

The conductive post 80 is disposed on the carrier 10. The conductive post 80 may be, or include, a pre-formed conductive post. The conductive post 80 includes a lower surface 801 b facing the carrier 10, an upper surface 801 u opposite to the lower surface 801 b and a lateral surface 801 s extended between the upper surface 801 u and the lower surface 801 b. In some embodiments, the dielectric layer 40 includes Polypropylene (PP), Polyimide (PI), Ajinomoto Build-up Film (ABF), other suitable insulating materials, or a combination of two or more thereof.

In some embodiments, the carrier 10 includes silicon (Si), ceramic, glass, metal, other suitable inorganic materials or a combination of two or more thereof. The carrier 10 may be a substrate, a wafer, or a lead frame. In some embodiments, each of the pad 60 and the conductive post 80 includes, for example, copper (Cu), other metal, a metal alloy, other conductive material, or a combination of two or more thereof. The adhesive layer 30 surrounds a portion of the lateral surface 801 s of the conductive post 80. In some embodiments, the adhesive layer 30 includes a conductive filler such as conductive particles (such as gold (Au), silver (Ag), Cu, another metal, a metal alloy, or other conductive material) and an adhesive (such as epoxy resin or other resin).

In some embodiments, a thermal degradation temperature (Td) of the adhesive of the adhesive layer 30 may be higher than a reflow temperature in a reflow process. A melting temperature of the adhesive of the adhesive layer 30 may be higher than the reflow temperature in the reflow process. For example, the melting temperature of the adhesive layer 30 may higher than about 260 Degrees Celsius (° C.). Thus, the adhesive layer 30 may not be melted or reflowed at a working temperature ranging from about 25° C. to about 260° C. during a reflow process. At least a portion of the lateral surface 801 s of the conductive post 80 may be surrounded by the adhesive layer 30, which has a relatively high melting point, may fix or support the conductive post 80 during thermal cycles in a process of manufacturing the semiconductor device package 1.

The conductive post 80 has a height H measured from the upper surface 801 u to the lower surface 801 b. In some embodiments, the height H ranges from about 410 micrometers (μm) to about 490 μm. The conductive post 80 has a width D1. In some embodiments, the width D1 ranges from about 270 μm to about 330 μm. The height H of the conductive post 80 is greater than the width D1 of the conductive post 80. The roughness of the lower surface 801 b may be different from the lateral surface 801 s. In some embodiments, the roughness of the lower surface 801 b is greater than the lateral surface 801 s. The ratio of the height H of the conductive post 80 to the width D1 of the conductive post 80 may be equal to or more than about 1.2:1, such as about 1.3:1 or greater, about 1.4:1 or greater, or about 1.5:1 or greater. The relatively great roughness of the lower surface 801 b of the conductive post 80 may enhance the adhesion and conductivity between the lower surface 801 b and the adhesive layer 30. In some embodiments, a relatively larger sized conductive filler (e.g., conductive particles) of the adhesive layer 30 is in contact with the lower surface 801 b and the pad 60. A relatively smaller sized conductive filler of the adhesive layer 30 may be fitted into the uneven surface 801 b of the conductive post 80 to mitigate a void issue at the lower surface 801 b of the conductive post 80.

The pad 60 is disposed between the carrier 10 and the conductive post 80. The dielectric layer 40 and the pad 60 are disposed on the carrier 10. The dielectric layer 40 defines an opening 401 p exposing the pad 60. The pad 60 can be a conductive pad. The conductive post 80 is electrically connected to the pad 60 through the adhesive layer 30. The conductive post 80 is electrically connected to the pad 60 by the adhesive layer 30 in the opening 401 p. In some embodiments, the conductive post 80 is not in direct contact with the pad 60, with a gap in between. In some other embodiments, at least a portion of the lower surface 801 b is in direct contact with the pad 60.

A difference between a length D2 of the opening 401 p of the dielectric layer 40 and a width D1 of the conductive post 80 may be equal to or greater than about 70 μm. The lower surface 801 b of the conductive post 80 is disposed within the opening 401 p. A portion of the conductive post 80 may be disposed on the dielectric layer 40. The difference between the length D2 of the opening 401 p of the dielectric layer 40 and the width D1 of the conductive post 80 may be greater than about 70 μm so that a portion of the lateral surface 801 s of the conductive post 80 can be surrounded and supported by the adhesive layer 30.

In some embodiments, one or more conductive posts may be slightly tilted with respect to a surface normal of a carrier. FIG. 2A is a cross-sectional view of a semiconductor device package 2 in accordance with some embodiments of the present disclosure.

FIGS. 7A-7C illustrate various stages of a method of manufacturing the semiconductor device package 1. Referring to FIG. 7A, a carrier 10 is provided. In some embodiments, the carrier 10 includes Si, ceramic, glass, metal, other suitable inorganic materials, or a combination of two or more thereof.

Referring to FIG. 7B, a pad 60 is disposed on the top surface of the carrier 10.

As used herein, the terms “approximately,” “substantially,” “substantial” and “about” are used to describe and account for small variations. When used in conjunction with an event or circumstance, the terms can refer to instances in which the event or circumstance occurs precisely as well as instances in which the event or circumstance occurs to a close approximation. For example, when used in conjunction with a numerical value, the terms can refer to a variation of less than or equal to ±10% of the numerical value, such as less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. Thus, the term “approximately equal” in reference to two values can refer to a ratio of the two values being within a range between and inclusive of 0.9 and 1.1.

Additionally, amounts, ratios, and other numerical values are sometimes presented herein in a range format. It is to be understood that such range format is used for convenience and brevity and should be understood flexibly to include numerical values explicitly specified as limits of a range, but also to include all individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly specified.

As used herein, the singular terms “a,” “an,” and “the” may include plural referents unless the context clearly dictates otherwise. In the description of some embodiments, a component provided “on” or “over” another component can encompass cases where the former component is directly on (e.g., in physical contact with) the latter component, as well as cases where one or more intervening components are located between the former component and the latter component.
